由于出现“ ImportError：没有名为六个模块的模块”，因此无法安装软件包

Question

I seem to have messed up my python install. I can't install new python packages:

$ pip install arq
Traceback (most recent call last):
  File "/usr/local/bin/pip", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/Users/me/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 48, in <module>
    import six
ImportError: No module named six

And trying to address this error directly gives the same error:

$ pip install six
Traceback (most recent call last):
  File "/usr/local/bin/pip", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/Users/me/Library/Python/2.7/lib/python/site-packages/pkg_resources/__init__.py", line 48, in <module>
    import six
ImportError: No module named six

I'm not really sure what to do. All pip operations seem to fail for the same reason. pip freeze and just pip give the same result.

I'm on osx.

This is inspired by @Christian Dean's comment. But I am on OSX so what I did was to just reinstall pip from here:
